Question: 692


What should you use to implement the code quality restriction on the release pipeline for the investment planning applications suite? A . a trigger

B . a pre deployment approval C . a post-deployment approval D . a deployment gate




Answer: B
Explanation:

When a release is created from a release pipeline that defines approvals, the deployment stops at each point where approval is required until the specified approver grants approval or rejects the release (or re-assigns the approval to another user).


Scenario: Code quality and release quality are critical. During release, deployments must not proceed between stages if any active bugs are logged against the release. References: https://docs.microsoft.com/en-us/azure/devops/pipelines/release/approvals/approvals



Question: 693


HOTSPOT


How should you confrere the release retention policy for the investment planning depletions suite? To answer, select the appropriate options in the answer area.


NOTE: Each correct selection is worth one point.





Answer:




Explanation:


Every request made against a storage service must be authorized, unless the request is for a blob or container resource that has been made available for public or signed access. One option for authorizing a request is by using Shared Key.


Scenario: The mobile applications must be able to call the share pricing service of the existing retirement fund management system. Until the system is upgraded, the service will only support basic authentication over HTTPS.


The investment planning applications suite will include one multi-tier web application and two iOS mobile application. One mobile application will be used by employees; the other will be used by customers.

Answer: A
Explanation:

Change the ConfigurationMode parameter from ApplyOnly to ApplyAndAutocorrect.


The Register-AzureRmAutomationDscNode cmdlet registers an Azure virtual machine as an APS Desired State Configuration (DSC) node in an Azure Automation account. Scenario: Current Technical Issue The test servers are configured correctly when first deployed, but they experience configuration


drift over time. Azure Automation State Configuration fails to correct the configurations. Azure Automation State Configuration nodes are registered by using the following command.

Contoso plans to improve its IT development and operations processes implementing Azue DevOps principles. Contoso has an Azure subscription and creates an Azure DevOPs organization.


The Azure DevOps organization includes:


-The Docker extension


You need to configure Azure Automation for the computer in Group7.


Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.





Answer:



Explanation:


Step 1: Create a Desired State Configuration (DSC) configuration file that has an extension of .ps1.


Step 2: Run the Import-AzureRmAutomationDscConfiguration Azure Powershell cmdlet The Import-AzureRmAutomationDscConfiguration cmdlet imports an APS Desired State Configuration (DSC) configuration into Azure Automation. Specify the path of an APS script that contains a single DSC configuration.


Example: PS C:>Import-AzureRmAutomationDscConfiguration -AutomationAccountName "Contoso17"-ResourceGroupName "ResourceGroup01" -SourcePath "C:DSCclient.ps1" -Force


This command imports the DSC configuration in the file named client.ps1 into the Automation account named Contoso17. The command specifies the Force parameter. If there is an existing DSC configuration, this command replaces it.


Step 3: Run the Start-AzureRmAutomationDscCompilationJob Azure Powershell cmdlet The Start-AzureRmAutomationDscCompilationJob cmdlet compiles an APS Desired State Configuration (DSC) configuration in Azure Automation.

Question: 707 DRAG DROP

You need to implement the code flow strategy for Project2 in Azure DevOps.


Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange in the correct order.





Answer:



Explanation:


Step 1: Create a repository A Git repository, or repo, is a folder that you’ve told Git to help you track file changes in. You can have any number of repos on your computer, each stored in their own folder.

Step 2: Create a branch Branch policies help teams protect their important branches of development. Policies enforce your team’s code quality and change management standards.


Step 3: Add a build validation policy When a build validation policy is enabled, a new build is queued when a new pull request is created or when changes are pushed to an existing pull request targeting this branch. The build policy then evaluates the results of the build to determine whether the pull request can be completed.


Scenario: Implement a code flow strategy for Project2 that will: Enable Team2 to submit pull requests for Project2. Enable Team2 to work independently on changes to a copy of Project2. Ensure that any intermediary changes performed by Team2 on a copy of Project2 will be subject to the same restrictions as the ones defined in the build policy of Project2.
